Polyvinyl Alcohol PVA 2088

Product Overview

PVA 2088 is a white or slightly yellow granule or powder in appearance with many properties:

1. Solubility: strong hydrophilicity, soluble in water (it can be slowly dissolved at room temperature, generally dissolved in hot water above 85°C), insoluble in almost all organic solvents. PVA 2088 will produce foam during the dissolution process, which can be solved by adding defoamer.

2. Film-forming: easy to form a film, and its film has excellent mechanical properties. PVA film has excellent barrier properties to H2, N2, O2 and other gases except H2O.

3. Adhesion: It not only has good adhesion with hydrophilic fibers, paper, etc., but also has good adhesion with hydrophobic fibers.

4. Thermal stability: When the sheet is heated to above 130°C, the appearance changes gradually. The partially alcoholylated PVA begins to melt at around 180-190 °C, and decomposes at 200 °C.

5. Solvent resistance: PVA has strong resistance to weak acid and weak alkali, and has good oil resistance.

Specification

Application

PVA 2088 is widely used in below industry:

1. Fiber processing industry: short spun yarn, long yarn and post-processing.

2. Film processing industry: use different processes to produce water-soluble films.

3. Coating mold industry: the fields of base fabric shaping and strengthening.

4. Paper processing industry: sizing and other fields.

5. Adhesive industry: re-wet bonding and other fields.

6. Stabilizer industry: vinyl acetate emulsion polymerization and other fields.

7. Others: cosmetics, pharmaceuticals, additives for building materials, temporary protective films, etc.

Packing and Storage:

Polyvinyl alcohol is packed in paper-plastic composite bag, net weight 25kg/bag, 18MT/20GP without pallets. Other packing 500kg/bag or 800kg/bag is as per customer’s requirements. PVA should be stored in a dry and well-ventilated room, away from heat sources, and avoid sunlight exposure. After opening the inner bag, it should be used up as soon as possible to prevent moisture and caking. In fact, as long as PVA is not in contact with water, it can be stored for a long time.
